DETACHABLE CLOSURE FOR BEQEPTACLES.

Application filed January 29,

Specification of Letters Patent.

Patented May 5, 1808. 1907. semi No. 354,632.

vented certain new and useful Improvements in Detachable Closures for Rece tareceptacle cles, of which the following is a specifica ion.

My invention relates to improvements in detachable closures for receptacles in which a disk is employed to cover the mouth of the receptacle and is held in close contact therewith by means of a yielding annulus of a sinuous" form.

The object of the invention is to provide an improved wire holding device to coact with a sealing disk to hold the latter in contact with the mouth of a rece tacle to efiect either a complete or a partial and which may be removedand replaced at will without the aid of tools.

The invention is applicable to receptacles of various kinds, such for example as bottles, or oil-cups where the closure is to be com lete, or in other cases where it is desired to effect only'a partial closure such as in sal,t,'pepper or sugar receptacles where the contents is to be discharged by sifting it through perforations in the disk.

The invention is illustrated in the accompanying drawing in which,

Figure 1 illustrates a plan views of the improved device.

device in connection with a perforated disk,

and Fig. 3 a side elevation of the same attached to a bottle neck, and showing in gienlines the horizontal position'the wire an ulus has when being placed in position. tical sectional View through a bottle neck and also through the closing device attached thereto, and shows in broken lines the tilted osition the wire annulusmust take when ing removed. Fig. 5 illustrates the device as applied to seal an oil cup.

Referring to the drawings by numerals, 1, designates a wire annulus comprising two series of uniformly-curved loops, 2, and, 3, the rounded points of one series of loops being in osition reverse with respect .to the rounded points of the other series. These two series of loops are formed from a continuous iece of wire, and

yiel ing slightly inde ndently of the others.

The upper series 0 wire loops, 3, lie flat or' .in a horizontal plane and above the lower series; the series of curved loops, 2, extend downwardly and the rounded points of this 'stood that the endl .horizonta closure of the v in the ends of the two Fig. 2 shows a plan view of the.

Fig. 4 a ver-' zontal each loop is capable of sl series are curved inwardly. The ends of the wire are permanently united in some suitable manner, as by solder, 11, and thus forms an endless ring or annulus, which never thereafter has the ends separated. It will-thus be underess wire annulus comprises two sets or series of uniformly-curved and annularly-arranged loops which have rounded oints,-one series, 3, belng in a Fplane and the'other series, 2, bein inclined slightly from a vertical plane-and also curved inwardly. I i

It will be noted that the curved ends of the horizontal loops, 3, project inward further than the curved ends of the loo 2, and thus the latter lie in a vertical la e outside of the ends of the loops, 3. 'his difference seriesof'loops provides a c rcular opening bounded bythe extremi-' -3 that is of a'smaller diameter than the opening bounded lay the ends of the loops, 2, and this diflference enables the disks to be placedin the annulus and held therein during handling.

The receptacles, 12,, should .be provided acent the rim or lip, 7, of the o ening or mouth of the receptacle and roun ed in the vertical direction; and immediately below the said rounded bead is a surrounding de pression, 8; the disk, 5, which closes the opening of the receptacle, except in F ig. 2, will seat u on the said rim or lip.

The endless wire annulus is especially con structed to admit of being fastened in osition upon the receptacle by placing it oriy in the position s own b broken lines in Fig. 3, and setting the rounded points of the lower series of loops, 2, upon the rim, or lip, 7, of the receptac e, and then simply pressing downward. This down pressure will cause the lower series of loopsto automatically expand sufliciently to pass over the rounded shoulder or head, 6, and then said loo s will automatically contract again and th loops, 2, will take the receptacle below the head, 6. -As the lower side of the said bead is rounded into this depression, the effect-of this construction is to cause the lower set'of Ioopsto be to enable them drawn downwardly which will press the upper set of loops, 3, hard u on the top surface of the sealingdisk, 5. p I on this endless wire annulus is to be removed from the.

receptacle in order to open the latter, the

better wayis to tilt one side upward, as indicated by. r'oken lines in Fig. 4; by forcing it i to tiltin this manner, the lowerloops, 2, 'will automatically 'exparicL' and their roundedends which are in the de res'sion, 8, of the receptacle, will let go or re ease.

receptacle, and the other operation of tilting it oil the receptacle to rem dve it, is new in this style of device,

In the closure shown inFig. 2, the closing disk, 9, has a-plurality of perforation's lfi, by

means of which the closure may be utilized as asiiter for salt, pepper or sugar receptacle.

Having thus described my invention what I claimas newand desire to secure by Letters Patent is,

1. A receptacle-provided with a rim and adjacent said rim having an exterior circumferential bead .rounded ina vertical direction; in combination with'a flexible disk resting on said rim, and an endless wire annulu s'formed into two continuousfseries. of

curving loops, the loops of theupper series being in a vertical plane betweentwo adj acent loops of the lower series and the loo s of the lower series being inclined downward y with their rounded ends lying in a vertical plane outside of the ends of the upper loops whereby the central circular opening .be tween the ends cf the lower loops will be of a greater diameter than the central opening .lhe operation here described of applying the endless wire annulus when closing the between the ends of the upper loops, and sa d wire annulus being yae ding in a W011; cumferentlal dlreotlon to permit 1ts repeated engagement with; and removal from the other series mcliningdownwardly and yieldingly engaging the rounded bead whereby to permit its repeated engagement with and to removal from said curved head '3. The combination with a receptacle provided with a rimand an exterior circumfen ential rounded bead adjacent'the rim, of a fle'r'rible disk seated on said rim, and a clamping ring'nomprising an annulus of permanent s ring loops normally of a smaller diameter .t an the bead on the receptacle and inde-" endently yielding in a lateral and oircumerential direction when forced over-said bead. v In testimony whereof I afiix my signature in presence of two witnesses v HUGH P., McMILLAN.- \Vitnesses:
